Variables
-
The objective of the 6 Months Harmonization Protocol was to define a list of core variables prospectively to be collected by the four mother and child randomized controlled trials to address the research aims of the HeLTI Initiative.
- Version
- 1.0
- Approach
- Prospective
- Type
- Quantitative
- Procedures
- Harmonized data is generated locally by studies (with the collaboration of the harmonization team).
- Participant Inclusion
- HeLTI participating mothers from the four studies
- Infrastructure
- Harmonized data must remain on study servers, but federated data analysis can be achieved
Information Content
The HeLTI 6 Months harmonized dataset includes information about:
- Socio-demographic and economic characteristics (household composition, employment status)
- Lifestyle and behaviours (alcohol use, tobacco use, drug use, Pittsburgh Sleep Quality Index (PSQI))
- Birth, pregnancy and reproductive health history
- Medication and supplements
- Adverse events (hospitalization, disability/incapacity, assault, homicidal behaviour, life-threatening conditions)
- COVID-19 (risk factors, symptoms, testing, diagnosis, self-isolation)
- Physical measures and assessments (weight, blood pressure)
- Administrative information

Harmonization
- Complete - study-specific variable is the same as DataSchema variable (status detail = identical) or needs transformation to generate DataSchema variable (status detail = compatible)
- Partial - categorical study-specific variable (status detail = proximate) or other types (status detail = tentative) could generate DataSchema variable but with loss of information
- Impossible - study does not collect DataSchema variable (status detail = unavailable) or cannot be used to generate DataSchema variable (status detail = incompatible)
- Undetermined - harmonization status not determined
- Not Applicable - harmonization status is not relevant
